DARWINISM APPLIED TO MAN 



General identity of human and animal structure — Rudiments and varia- 

 tions showing relation of man to other mammals — The embryonic 

 development of man and other mammalia — Diseases common to man 

 and the lower animals — The animals most nearly allied to man — 

 The brains of man and apes^External differences of man and apes — 

 Summary of the animal characteristics of man — The geological 

 antiquity of man — The probable birthplace of man — The origin of 

 the moral and intellectual nature of man — The argument from 

 continuity — The origin of the mathematical faculty — The origin of 

 the musical and artistic faculties — Independent proof that these 

 faculties have not been developed by natural selection — The inter- 

 pretation of the facts — Concluding remarks. 



Our review of modern Darwinism might fitly have terminated 

 with the preceding chapter ; bnt the immense interest that 

 attaches to the origin of the human race, and the amount of 

 misconception which prevails regarding the essential teachings 

 of Darwin's theory on this question, as well as regarding my 

 own special views upon it, induce me to devote a final chapter 

 to its discussion. 



To any one who considers the structure of man's body, 

 even in the most superficial manner, it must be evident that 

 it is the body of an animal, differing greatly, it is true, from 

 the bodies of all other animals, but agreeing Avith them in all 

 essential features. The bony structure of man classes him as 

 a vertebrate ; the mode of suckling his young classes him as 

 a mammal ; his blood, his muscles, and his nerves, the structure 

 of his heart Avith its veins and arteries, his lungs and his whole 

 respiratory and circulatory systems, all closely correspond to 

 those of other mammals, and are often almost identical with
